You need to carry enough water to make it to the next trail head there is cistern water about every 5 miles on the tow path, but I don't drink it, although others do. Major trail heads are about 30 miles apart on both the GAP and the C&O. I carry 2L of water for that distance in bottles. My wife on the other hand uses the same amount in a camelback. When are you leaving and from where? Wife and I leave tomorrow From Point Park,Look me up if your nearby, I' have a red helmet and yellow or blue shirt on, weather depending.
